TL;DR: In this article, various ambient energy harvesting technologies (solar, thermal, wireless, and piezoelectric) are reviewed in detail and their applicability in the development of self-sustaining wireless platforms is discussed.

TL;DR: A benchmarking prototype of an embedded microcontroller-enabled sensor platform has been successfully powered by an ambient ultrahigh-frequency (UHF) digital TV signal where a broadcasting antenna is 6.3 km away from the proposed wireless energy-harvesting device.

TL;DR: In this article, a dual-band rectenna operating at 915 MHz and 2.45 GHz was proposed, which is optimized for low input power densities using harmonic balance (HB) simulation.

TL;DR: A dual-band rectifier based on RCN is designed and characterized showing improved performance in comparison with a conventional dual- band envelope detector by exhibiting improved RF-dc conversion efficiency and reduced sensitivity versus output load and input power variations.

TL;DR: In this paper, a review of existing works and solutions in the field of solar/electromagnetic energy harvesting and wireless power transmission is presented, where solar antenna structures are used to obtain a compact implementation, direct current (dc) combining circuits necessary to combine the outputs of the solar and the electromagnetic harvesters, and efficient solar-to-electricromagnetic (EM) converters that can be used to synthesize autonomous wireless-power transmission radiofrequency (RF) signal generators.
